ANNEALlNG-BOX.

SPECIFICATION forming part of Letters Patent No. 302,688, dated July 29,1884.

Application filed April 21, 1884. (No model.)

Be it known that we, J AMEs MoNEIL and TrroMAs MONEIL, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have jointly invented or discovered a certain new and useful Improvement in Annealing-Boxes, of which improvement the following isa specification.

In theaccompanying drawings, which make part of this specification, Figure l is a view in perspective of an annealing-box embody ing our invention; Fig. 2, a vertical longitudinal central section through a portion of the same, and Fig. 3 a vertical transverse section through the same.

Annealing boxes employed for covering sheet-iron or other articles in annealing-furnaces, as heretofore constructed, have been subject to the objections of being liable to be warped or distorted by'their own weight under the intense heat to which they are eX- posed when in use; and, further, that worn or burned-out portions could not be properly renewed or repaired, and consequently wear or injury of a portion of the box involved a waste of comparatively serviceable metal in the remainder.

It is the object of our invention to provide an annealingbox which shall possess the ca pacity of effectually resisting warping or def; ormation by heat, and in which the renewal of any particular portion may be readily cf fected as required, so as to retain the use of the remainder as long as in a serviceable condition.

The improvements claimed are hereinafter fully set forth.

versely at intervals throughout its length by the flanges of the several sections, which serve both as braces and connecting-pieces, and is thereby prevented from bending or warping under the action of heat, and the removal of any of the sections, if worn or injured, can

be readily effected, whenever desired, by cutting out the rivets to admit of replacement by a new section, which is similarly secured in place.

The flanges 2 may either be bntted directly together, or, for the purpose of affording addi- 6o tional strength and stiffness to the boX, bracebars 5, bent into form corresponding with the flanges, may, as shown in the drawings, be interposed between the sections, and united thereto by rivets passing through said braceboilers, have been heretofore known, and such,

therefore, we do not broadly claim.

WVe claim herein as our invention a 1. In an annealing-box, the combination of a series of open-bottomed U-shaped sections having flanges turned on each of their ends,

a series of transverse brace -bars bent into similar form with and interposed between the flanges of the adjacent sections, a pair of end plates, and rivets passing through the flanges of the sections and through the brace-bars and connecting the sections one to another and to the end plates, substantially as set forth.

2. In an annealing-box, the combination of a seriesof flanged sections, transverse bracebars interposed between the flanges of the adjacent sections, a pair of end plates or heads, bottom bars abutting against the sections and, heads, and connecting-rivets, substantially as set forth.'

- In testimony whereof we have hereunto set 9 5 our hands.
